Abstract

The invention discloses a production method of high-gloss and high-covering-capability rutile titanium dioxide. The production method comprises the steps of preparing metatitanic acid slurry, sequentially adding a magnesium-containing compound, a zirconium-containing compound and a potassium-containing compound to prepare titanium dioxide primary slurry, then sequentially adding a titanium-containing compound and an aluminum-containing compound, and finally filtering, washing, drying and crushing to obtain high-gloss and high-covering-capability rutile titanium dioxide. According to the production method, saline matters such as magnesium salt, zircon salt, kali salt and the like are added in metatitanic acid, so that the effect of improving the high covering property of titanium dioxide can be achieved; and the surface treatments of hydration of titanium dioxide and hydration of titanium dioxide, and the like can be conducted on the surface of titanium dioxide, so that the effect of improving the gloss of titanium dioxide can be achieved, and the gloss and the covering capability of titanium dioxide are all improved greatly.

Description

technical field

[0001] The invention relates to a production method of titanium dioxide, in particular to a production method of high gloss and high covering rutile titanium dioxide. Background technique

[0002] Titanium dioxide pigment is an excellent white pigment, which has the advantages of high whiteness, high opacity, stable physical and chemical properties, etc., and is widely used in coatings, plastics, inks and other industries.

[0003] As one of the application fields of titanium dioxide pigment, titanium dioxide for ink has high requirements on gloss and hiding power. The ink layer is thinner than ordinary coatings, often only a few microns thick. Therefore, such a thin ink layer needs to be made To high gloss and high hiding, this puts forward high quality requirements for titanium dioxide.

[0004] Patent EP0406194 discloses a production method for producing high gloss and high weather resistance titanium dioxide. This patent mainly uses zirconium, phosphoru...
